Why an eSIM is Recommended for Sri Lanka
No Free EU Roaming
Unlike European countries, Sri Lanka does not benefit from free EU roaming. Your home plan will be expensive: between $2 and $5 per MB depending on your carrier. For a one-week trip with moderate usage (browsing, social media), you can easily spend $50 to $100 on roaming.
Free WiFi vs eSIM
Free WiFi is indeed widespread in Sri Lanka (hotels, cafes, tourist areas), but it has risks:
- Security: unsecured public networks, hacking risks
- Reliability: unstable connections, frequent dropouts
- Mobility: impossible to use while traveling (transport, excursions)
An eSIM offers secure and reliable connectivity everywhere, even in remote areas.
